//  "Integer Compression" variable simple "SimpleV"
//	this belongs to the integer compression known as "simple family", like simple-9,simple-16
//	or simple-8b. SimpleV is compressing integers in groups into variable word size 32, 40 and 64 bits + RLE (run length encoding) 
//	SimpleV is faster than simple-16 and compress better than simple-16 or simple-8b.
